Learn PowerPoint 2013 for Windows: Emphasis Animations

Emphasis Effect animations determine how the slide object calls attention to itself while it is on-the-slide. Entrance and Exit effect animations allow a slide object to enter or exit the slide area, whereas slide objects with Emphasis Effect animations are already there on the slide area before they start animating, and will be there even after they have finished animating. Typical Emphasis Effects are Spin and Grow/Shrink. You can also apply Emphasis Effect animations to text objects so that the fonts or the text colors change.
